For developers: what the fix changed

The fix improves markup sanitisation by escaping untrusted strings in `LinksPropType`, `StringPropType`, `FieldPropertySource`, and `TokenSource`, and by using `#plain_text` instead of `#children` with `Markup::create()` for plain strings in `SlotPropType`. It also overrides Twig's `include()` function in `TwigExtension` to return a `Markup` object for consistent trust boundaries.

Also in this release The release also refactored plugin managers, added a `no_ui` property to sources, introduced a `SourceTags` enum, and improved test performance.

2.0.16 to 2.0.17 10 commits, 128 files including 80 tests.

Get in touch

Tell me who you are, what your organisation does, and what you need. That might be a Drupal site that needs looking after, an upgrade to get done before December, or an agency that needs Drupal cover.

If I can help, I'll say so and suggest a call. If I can't, I'll tell you straight away rather than waste your time.

For context: I work mainly with UK charities, membership bodies and research organisations, and with the agencies that look after their websites. Not recruiters.

Or start smaller and connect with me on LinkedIn. That's where I post what I find digging around in charity and grants data, and where the free tools turn up first.
